BASE FOR BARBERS CHAIRS.

SPECIFICATION forming part of Letters Patent No. 687,760, dated December3, 1901. Application filed June 14, 1901. Serial No. 64,499. (No model.)

To all whom it may concern.-

Be it known that I, ERNEST E. KOKEN, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Bases for Barbers Chairs, ofwhich the following is a full, clear, and exact specification, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, formingpart of this specification.

This invention relates to new and useful improvements in bases orpedestals for barbers, dentists, and other revoluble chairs, and isespecially adapted for use with hydraulic chairs of this character. Itsprimary object is to provide a firm and compact structure'capable ofeasy ornamentation and which is so constructed as to prevent theaccumulation of clippings and other debris in inaccessible-places belowthe chair.

I ith this and other objects in view the invention consists in the novelconstruction and combination of parts hereinafter more fully describedand claimed, and illustrated in the accompanying drawings, showing thepreferred form of my invention, and in which- Figure 1 is a perspectiveview of the pedestal. Fig. 2 is a central vertical section therethrough.Fig. 3 is a detail view of the drum surrounding the cylinder or core ofthe pedestal; Fig. at, ofthe upper part of said cylinder or core; Fig.5, of the upper part of the bell. Fig. 6 is a bottom view of the ring,and

Fig. 7 of the base-casting.

Referring to the figures by numerals of reference, 1 is a cylindricalcore adapted to c0ntain the hydraulic valves and operating mechanism(not shown) and which is provided at its upper end with an annularflange 2, beneath which are arranged a series of angular ribs 3. Thisupper end of the core is dished, as at 4, for the reception of theconnecting parts of the chair, and the outer face of the lower portionof the core is tapered downward, as shown at 5. A groove or recess 6extends around the tapered portion of the core and forms a bead 7 ateach end of said tapered portion. Beads 8 are also formed in a similarmanner at the ends of the perpendicular portion of the outer face of thecore, an annular recess 9 being arranged therebetween.

The lower tapered end 5 of the core is fitted with a collar 10, whichextends upward from the center of a base-casting 11. This collar isprovided with a tapered bore, so as to form a bearing for the beads 7 ofthe core. The internal taper is preferably obtained by molding Babbittmetal, lead, or other soft fusible metal 12 about a form of the propershape, the same being retained in position by flanges 13, extendinginwardly from the ends of the collar 10.

A circular disk 14 rests'upon the casting 11 and incloses the collar 10.This disk may be provided with a suitably-ornamented surface, and theouter edge thereof issecured to the casting by means of a ring 15,preferably of brass. This ring has lugs 16 formed thereunder, whichreceive screws 17, inserted through the casting, as shown. 4

A bell 18, formed of suitably-ornamented metal, rests upon the disk 14and extends over the upper end of the collar 10. The core 1 extendsupward through this bell, and that portion thereof which is above thebell is inclosed by a cylinder or drum 19, formed or ornamented withwood or other material. This drum contacts with the beads S and bears atits lower end upon the bell 18, said bell being provided with a flange(or projections) 20, which serves to hold the parts in proper position.i

A ring 21, which is Lshaped in cross-section, is arranged upon the topof the drum, and the flange 2 of the core bears thereupon, therebyholding the parts securely bound together. The ribs 3, before referredto, are fitted with grooves 24., formed in the inner edge of the top ofthe drum.

In order to prevent upward movement of the core 1, a set-screw 22 isarranged within the collar 10 and extends above and into the path of thelower bead 7 of the core. Access to this screw 22 can be obtainedthrough an aperture 23, formed within the base-casting.

By providing the drum 19, the bell 18, and

disk 14 the heavy portions of the pedestal, which cannot be readilyformed. with ornaments, are completely covered by light ornamentalpieces.

It will be seen that the parts of the pedestal are compact and securelybound together, and as no apertures are formed therein it is impossiblefor clippings or other debris to accumulate therein.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein Without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fallwithin the scope of my invention.

Having thus described myinvention, What I claim as new and useful, anddesire to secure by Letters Patent, is

1. The combination with a base; of a core fitted thereto and extendingthereabove, a cover to the base, a bell upon the cover and inclosing thecore, a drum upon the bell and inclosing the core and means for bindingthe parts together.

2. The combination with a base; of a collar thereto, a core fittedwithin, and extending from the collar, a cover to the base, a bellthereon inclosing the core and extending over the collar, a druminclosing the core and bearing upon the bell and means for binding theparts together.

3. The combination With a base; of a collar thereon, a soft-metal,tapered bore to the collar, a core having a tapered end fitted withinthe collar, annular beads upon said end bearing upon the tapered bore ofthe collar, and a set-screw inthe collar and projecting into the path ofone of said beads.

4. The combination with a base; of a collar thereon, a soft-metaltapered boreto the collar, a core having a tapered end fitted Withinthecollar, annular beads upon said end bearing upon the tapered bore of thecolwas lar, a set-screw in the collar and projecting into the path ofone of said beads, a cover to the base, means for securing the sametogether, a bell upon the cover and inclosing the core, said bellextending over the collar, a drum upon the bell and inclosing the core,and a flange to the core overlapping the drum.

5. The combination with a base; of a collar thereon, a soft-metaltapered bore to the collar, a core having a tapered end fitted withinthe collar, annular beads upon said end bearing upon the tapered bore ofthe collar, a set-screw in the collar and projecting into the path ofone of said heads, a cover to the base, means for securing the sametogether, a bell upon the cover and inclosing the core, said bellextending over the collar, a drum upon the bell and inclosing the core,a flange to the core overlapping the drum, ribs to said core engagingthe drum, and a ring intermediate the flange and drum.

6. The combination with a base having a collar thereon, of a core fittedinto and eX-. tending from the collar, means for locking the core in thecollar, a disk upon the base, a ring engaging the edge of the disk andsecured to the base, a bell upon the disk and inclosing the core, saidbell extending over the collar, a drum upon the bell and inclosing thecore, a flange to the core overlapping the drum, ribs to said coreengaging the drum, and a ring intermediate the flange and drum,substantially as described.

In testimony whereof I have hereunto affiXed my signature, in thepresence of two Witnesses, this 22d day of May, 1901.

ERNEST E. KOKEN.
